The present invention relates to an emulsification method and an emulsification apparatus, capable of attaining easy control of particle size and particle size distribution, and simple scale-up and maintenance, and providing an emulsifying amount sufficient for industrial production. Namely, the method comprises continuously and successively passing two or more types of liquids which are substantially immiscible with each other through two or more mesh members disposed at certain intervals in the presence of an emulsifier to thereby perform emulsification, and the emulsification apparatus as an apparatus for carrying out the method comprises liquid feed pumps for feeding two or more types of liquids which are substantially immiscible with each other, and a cylindrical flow passage to which the two or more types of liquids are fed by the liquid feed pumps, the cylindrical flow passage including a predetermined number of wire gauzes disposed therein at a predetermined interval.

A tap with drill includes a drill portion including a plurality of chip discharge grooves and having drill blades for cutting a prepared hole. The tap further includes a tap portion for cutting the internal thread on an inner circumferential surface of the prepared hole formed by the drill blades, and oil holes. The tap with drill is applied for performing cutting work. The drill blades and thread cutting edges include three blades formed along chip discharge grooves, respectively. The oil holes are helically formed in three with the same leads as the chip discharge grooves and opened at relief surfaces of the drill blades, respectively. The chip discharge grooves straddle the drill portion and the tap portion in fixed groove sectional shapes and have negative lands swelled into grooves.

An anti-blocking agent master batch is provided, obtained by compounding 100 parts by mass of a polyolefin-based resin with 1 to 40 parts by mass of polymer fine particles, the polymer fine particles obtained by: causing two or more fluids including a liquid medium, a monomer or monomers, and a polymerization initiator to continuously and successively pass through a plurality of net bodies which are disposed at given intervals in a cylindrical passage and each have a surface crossing a direction of the passage to obtain an emulsion including liquid droplets containing the monomer or monomers and the polymerization initiator, the liquid droplets being dispersed in the liquid medium; and heating this emulsion to polymerize the monomer or monomers. Also provided is a manufacturing method thereof. The anti-blocking agent master batch can prevent the generation of die build-up during the manufacture of a master batch for a polyolefin-based resin film by compounding an anti-blocking agent into a polyolefin-based resin.

An electric drive device control system includes an electric drive device and an electric control unit. The electric control unit stores a control-side correction current for compensating for a current deviation of the electric control unit and a drive-side correction current for compensating for an operation deviation of the electric drive device. The electric control unit updates the drive-side correction current to a new drive-side correction current, which is specific to a new electric drive device, when the electric drive device is replaced with the new electric drive device. The electric control unit also updates the control-side correction current to a new control-side correction current, when the electric control unit is replaced with the new electric control unit.
摘要:
A hydraulic control system of a friction device where fail-safe is required is provided with one oil pressure switch and one pressure changeover valve. The pressure changeover valve is switched by auxiliary oil pressure based on an operation of the oil pressure control valve. When an auxiliary port communicates with an input port and the pressure changeover valve is switched to the filling determination side, the oil pressure switch is turned on and “filling determination” can be carried out. When the auxiliary port is disconnected from the input port, the pressure changeover valve is switched to the fail-safe determination side. The oil pressure switch is supplied with the same driving oil pressure as of the friction device and “fail-safe determination” can be carried out from the on/off state of the oil pressure switch.
摘要:
A position sensor for an automatic transmission has multiple switches, each of which generates “ON” or “OFF” signal depending on a selected position of a shift lever. Signal patterns (“ON” and “OFF” signals) of the normal operation are memorized as a map of signal patterns in a first memory portion. A second memory portion memorizes the respective signal patterns at the respective selected positions of the shift lever. The signal pattern and the change of the signal patterns in the second memory portion are compared with those memorized as the map of the signal pattern in the first memory portion, and determines that a malfunction has occurred in the position sensor, if at least one of the signal patterns and the changes of the signal patterns does not coincide with any of those memorized the map of the signal pattern. The malfunction of the position sensor can be surely detected at an earlier stage of operation of the shift lever for the automatic transmission.

The present invention relates to conjugates of a lipid, substrate peptide of an enzyme secreted from the cells of mammals, including humans, and a water-soluble polymer that can be used as colloidal carriers and the like of tissue-specific drug delivery systems, methods of producing these conjugates, peptide-water-soluble polymer conjugates optionally having protective groups that are useful as the intermediates of these conjugates, colloidal carriers made from these conjugates, and tissue-specific drug delivery systems that use these colloidal carriers.
摘要:
A plurality of nozzles forms the first row of nozzles, the second row of nozzles, the third row of nozzles and the fourth row of nozzles, which extend in parallel with a sub scanning direction. A black ink is adapted to be supplied to one row of nozzles. Color inks are adapted to be supplied to the other rows of nozzles, the color inks being different for each of the other rows of nozzles. Positions of the second row of nozzles to the fourth row of nozzles are shifted by ⅓ or ⅔ of an arrangement pitch of the nozzles, in the sub scanning direction, for each of the rows of nozzles, with respect to positions of the first row of nozzles. In a high-speed black mode, the color inks are ejected from corresponding nozzles, in connection with ink ejection of the black ink from corresponding nozzles.
